M33.19 is a billable diagnosis code used to specify a medical diagnosis of other dermatomyositis with other organ involvement. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Clinical Classification

Clinical Information

  • Dermatomyositis

    a subacute or chronic inflammatory disease of muscle and skin, marked by proximal muscle weakness and a characteristic skin rash. the illness occurs with approximately equal frequency in children and adults. the skin lesions usually take the form of a purplish rash (or less often an exfoliative dermatitis) involving the nose, cheeks, forehead, upper trunk, and arms. the disease is associated with a complement mediated intramuscular microangiopathy, leading to loss of capillaries, muscle ischemia, muscle-fiber necrosis, and perifascicular atrophy. the childhood form of this disease tends to evolve into a systemic vasculitis. dermatomyositis may occur in association with malignant neoplasms. (from adams et al., principles of neurology, 6th ed, pp1405-6)
  • Adult Dermatomyositis

    dermatomyositis in an adult.
  • Childhood Dermatomyositis|JDM|JDM|Juvenile Dermatomyositis|Juvenile Dermatomyositis

    an inflammatory myopathy of childhood resulting in muscle weakness, and associated with a characteristic skin rash.
  • Cutaneous Dermatomyositis Disease Area and Severity Index|CDASI|CDASI

    an instrument that measures activity and damage in the skin of dermatomyositis patients.
  • Dermatomyositis

    inflammation of the skin and muscle.
  • Dermatomyositis Skin Severity Index|DSSI|DSSI

    an assessment of disease activity in the skin of patients with dermatomyositis.
  • Interferon-Induced Helicase C Domain-Containing Protein 1|CADM-140 Autoantigen|Clinically Amyopathic Dermatomyositis Autoantigen 140 kDa|EC 3.6.4.13|Helicard|Helicase with 2 CARD Domains|IFIH1|Interferon-Induced With Helicase C Domain Protein 1|MDA-5|Melanoma Differentiation Associated Protein-5|Melanoma Differentiation-Associated Protein 5|Murabutide Down-Regulated Protein|RLR-2|RNA Helicase-DEAD Box Protein 116

    interferon-induced helicase c domain-containing protein 1 (1025 aa, ~117 kda) is encoded by the human ifih1 gene. this protein is involved in the positive regulation of antiviral responses.
  • Juvenile Dermatomyositis Sine Myositis|Juvenile Amyopathic Dermatomyositis|Juvenile Amyopathic Dermatomyositis|Juvenile Dermatomyositis sine Myositis|Juvenile dermatomyositis without myopathy

    a rare form of juvenile dermatomyositis that manifests with characteristic cutaneous findings for at least six months in the absence of any detectable muscle involvement.
  • Juvenile Dermatomyositis with Myopathy|Juvenile dermatomyositis with myopathy

    evidence of juvenile dermatomyositis with myopathy.
  • Juvenile Dermatomyositis with Other Organ Involvement|Juvenile dermatomyositis with other organ involvement

    evidence of juvenile dermatomyositis with other organ involvement.

Patient Education


Myositis

Myositis means inflammation of the muscles that you use to move your body. An injury, infection, or autoimmune disease can cause it. Two specific kinds are polymyositis and dermatomyositis. Polymyositis causes muscle weakness, usually in the muscles closest to the trunk of your body. Dermatomyositis causes muscle weakness, plus a skin rash.

Other symptoms of myositis may include:

  • Fatigue after walking or standing
  • Tripping or falling
  • Trouble swallowing or breathing

Doctors may use a physical exam, lab tests, imaging tests and a muscle biopsy to diagnose myositis. There is no cure for these diseases, but you can treat the symptoms. Polymyositis and dermatomyositis are first treated with high doses of a corticosteroid. Other options include medications, physical therapy, exercise, heat therapy, assistive devices, and rest.
